Hey Al,
I solved it with the following config:
setupcomplete.cmd
for %%i in (C D E F G H I J K L M N O P Q R S T U V W X Y Z) do if exist %%i:\sources\install.wim set CDROM=%%i:
copy %cdrom%\WPI\WPIRUN.cmd "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup" /Y
del %0
WPIRUN.cmd
for %%i in (C D E F G H I J K L M N O P Q R S T U V W X Y Z) do if exist %%i:\sources\install.wim set CDROM=%%i:
REG add "HKCU\Software\Microsoft\Internet Explorer\Download" /v "CheckExeSignatures" /d "no" /f
REG add "HKCU\Software\Microsoft\Internet Explorer\Download" /v "RunInvalidSignatures" /t "REG_DWORD" /d 1 /f
REG add "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Attachments" /v "SaveZoneInformation" /t "REG_DWORD" /d 1 /f
REG add "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Associations" /v "LowRiskFileTypes" /d ".cmd;.exe;.hta;" /f
reg import %cdrom%\wpi\software\Tools\NetzwerkinstallationEXE.reg
regedit /s %cdrom%\wpi\software\Tools\NetzwerkinstallationEXE.reg
REM create automatically a networkdrive (works only if the share is not password-protected)
PUSHD \\192.168.x.xxx\DEPLOY
REM Start WPI and wait until it was closed
Start "running WPI..." /Wait WPI\wpi.exe
REM removes the networkdrive
